The present application relates to the technical field of biological information, and particularly relates to a non-small cell lung cancer medical data mining method.The data mining method detects blood samples of patients before medication, avoids invasive tissue sampling of patients, and compared with the limitation of a traditional method which only relies on a small number of indexes (such as gene expression, mutation, etc.), complex data at a single cell level are used to ensure the robustness of a deep learning model.

Systems, devices, and methods for planning an ultrasound-guided tissue sampling procedure are disclosed. An exemplary system comprises an ultrasound imaging device for generating ultrasound images of an anatomical target in a real-time ultrasound field of view (FOV), a display for showing the ultrasound images, and a control unit. Before a tissue sampling device is extended into the ultrasound field of view, the control unit displays graphical user interface elements (UIEs) that show a predicted nominal trajectory of the sampling device intersecting the anatomical target object in the ultrasound field of view. As the tissue sampling device is extended into the ultrasound field of view, the control unit determines one or more real-time trajectory parameters and updates the UIEs.The control unit displays the updated UIEs to provide visual feedback on whether the tissue sampling device will intersect the anatomical target.

Systems, devices, and methods for determining a sample collection device for use in an ultrasound-guided endoscopic tissue sampling procedure are disclosed. An exemplary system comprises an ultrasound imaging device for generating ultrasound images of an anatomical target in a real-time ultrasound field of view (FOV), a display for showing the ultrasound images in the ultrasound field of view, and a processor. Based on the position of the anatomical target in the ultrasound field of view, the processor predicts, from several nominal sample collection device trajectories, a nominal trajectory that intersects the anatomical target. The several nominal trajectories correspond to different hardware configurations of the several nominal sample collection devices.The processor determines a recommendation for a sampling device with a hardware configuration according to the predicted nominal sampling device trajectory.

In an embodiment of the invention, a frictional tissue sampling device for obtaining a histological sample from an epithelial layer includes a platform with an axis, an abrasive material comprising a plurality of fibers associated with the platform, where the abrasive material is adapted to abrade the epithelial layer to dislodge the histological sample, where rotation of the platform around the axis rotates the abrasive material, and a collector material comprising a plurality of loops associated with the platform, where rotation of the platform around the axis rotates the collector material, where the collector material is adapted to collect the histological sample dislodged by the abrasive material, where contacting the platform with the epithelial layer and rotation of the platform moves the abrasive material and the collector material over the epithelial layer thereby obtaining the sample.

This invention discloses a placental tissue sampling robot, comprising a support frame, a support platform, an identification device, and a moving device. The support platform is mounted on the support frame. The identification device is mounted on the support frame, facing the support platform, and is used to identify and locate the required cutting position of the placenta. The moving device is mounted on the support frame, and its moving end is equipped with a clamping component, which is located above the support platform. Both clamping ends of the clamping component are equipped with cutting components. The moving device controls the cutting components to cut the placenta at the designated cutting position based on the identification and positioning of the required cutting position by the identification device. A frame-shaped cutting section is provided on the side of each cutting component facing the other. When the clamping component is closed, the two frame-shaped cutting sections are tangent to remove a placental sample of the corresponding frame size. Through these features, the robot can automatically avoid unsampling areas and achieve automated cutting and sampling of precise sampling points in safe, non-calcified areas.
